Can black agate and obsidian be worn together?

You can wear it like this. It's a good combination. Because black agate can resist spells and bad aura, while obsidian can absorb negative energy (bad aura and energy), in this case, it is equivalent to wearing bulletproof vests and holding weapons in hand. The external bad energy can't get in, and your own bad energy can be eliminated quickly. This is a good match. However, 100% of black agates on the market are artificially colored, and natural agates are used for artificial coloring treatment, because natural agates are not black, and the structure of agates is easy to be colored, and those very red agates are almost all artificially heated or colored. Natural agate is lighter in color, and natural red agate is less.
